GABBONATED-WATER COOLER.

Application filed Ju1y 20, 1925. Serial No. 44,787.

This invention relates to improvements in a cooling apparatus for carbonated water in soda fountains. etc, and more particularly to an apparatus so formed that the mixture 5 of gas and water is maintained at all times in said cooler.

One of the objects of said cooleris to form a reservoir of carbonated water in the refrigerating chamber and to eliminate from said reservoir all pockets now usually pres ent and in which gases separating from the water accumulate.

A further object is to so arrange a plurality of said chambers that during the time the outlet from said chambers is open and aetlow of liquid through the device is established, all gases liberated by such flow will be successively projected and intermingled in each succeeding chamber in a manner to thoroughly intermingle said escaped gases and project them back into the water again.

A further object of the invention is to so arrange the above mentioned chambers that the necessity of snifting any of these chambers is eliminated.

Another object of the invention resides in providing a device having a plurality o chamber forming members which are assembled with retaining parts to form a plurality of closed intercommunicating chambers between an inlet and an outlet having means therein for delivering fluid from the top of one chamber to the bottom of the next throughout all of the chambers for producing an upward flow of the fluid in each chamber in order that a plurality of fluids flowing through said chambers will be thoroughly comingled and prevented from separation due to difference in specific gravity.

The invention includes other objects and advantages in thoroughly comingling fluids passing therethrough aside from the structural relation of the parts designed to produce a readily assembled device which may be manufactured economically as more particularly pointed out in the following detailed description and claim directed to the preferred forms of the invention it being understood, however, that numerous other cu'ibodimcnts of the invention may be made which are within the scope of the invention as herein set forth.

In the drawings forming part of this application,

f gas and liquid Fig. 1 .is a central vertical longitudinal sect-ion of cylinder construction showing the invention in a preferred embodiment.

, .Fig. 2 is an end elevation of the same, looking from the top of the structure illustrated in Fig. 1.

Referring to the drawings a plurality of hollow cylinders are indicated by the numeral 15 which are mounted in spaced parallel relation in a substantially horizontal plane and in which are formed the closed chambers. A pair of endsections 17 and 19 are provided for receiving the opposite ends of the cylinders 15 in forming an assembled unit structure. The end section 17 is formed with a plurality of cylindrical recesses 16 as more clearly shown in Fig. 2 for receiving the ends of the cylnders 15 and forming one closed end for the chambers within the cylinders, while the recesses 20 in the end section 19 receive the opposite ends of the hollow cylinders 15and close the same in liquid tight relation. The connection between the cylinders 15 and the end sections 17 and 19, respectively may be of any suitable form but is of a rigid character to provide closed tight chambers within each. of the hollow cylinders and to form an assembled unitwhen the parts are in the relation shown in Fig. 1. Y

The end section 19 is formed adjacent one end thereof and on the upper edge with a threaded projection 28 which forms an outlet connection for the unit while the lower edge of the opposite end is formed with a similar threaded projection 18 providing an inlet connection; The upper edge of the section 19 is also formed with an upwardly pro jectingbody portion indicated by the numeral 21 which is formed with a pair of 95 transfer chambers 22 sealed against the passage of liquid by the cover plates 23. Passages 24: are formed in the end section 19 communicating with the top portion of adjacent chambers formed in the hollow cyl- 10o indors 15 as more particularly shown in Fig.

1, these passages being at one end portion of the transfer chambers 22, while pipes 25 are mounted in the end section 19 and communicate with the opposite ends of the transfer 105 chambers 22. These pipes25 extend downwardly to the lower portions of adjacent chambers formed in the hollow cylinders 15 and terminate adjacent the bottom portions thereof, said pipes being provided at their no lower ends with beveled portions indicated at 26. The outlet 28 of the upper end section 19 is formed with an outlet passage 27" ofsmaller diameter than the inlet pipe 25 structure above described in, that. thefiuid flowsupwardly through each; cylinder. successively'from theinlet tothe outlet andis dc? livered from, one chamber. to the next adja.-. cent chambers. through. one of thetransfer. chambers 22. and? one of" the pipes. 25.. to the lower end ofthe next adjacent chamber. wllereit. again. flows. upwardly in. order. that. a. thorough] intermingl-ing of the fluids pass; in g. thereth rough is maintained.

hile this. unit structure or assembly is. designed more particularly for use. in con nection, with a, cooling; device for. carbonated water adapted to. maintain the. gas intermine gled with the liquid. and eliminate. snifterv valves, it is to ,be understood that. it. will efficiently operate to maintain. any fluids thor-. ough-ly intermingled in which some of the fluids have a. considerably different, specific gravity, fromthe others inview of, thespe; cific mannerof treating the same inforcing them to. travelfromthe bottoin to the topof. each closed chamber.

Itis to.beparticularly noted that a, rela: tively simple assembled unit is. providedin which ,the hollow cylinders and the end seetionsform the main chambers ofthestruc: ture andin whichvupon theassemblyof the end sections; with thecylinders, allof the.

parts aremounted in assembled operative1e lation.

vWhere, two liquids of different, specific gravity or a gas and a. liquid such as charged water used at soda fountains, are used, the fluids are continually and effectively mixed or comingled. during their upwardflow through thecylinders so..that the lighter fluids are prevented from separating from the heavier fluids by being successively delivered at the bottom of each chamber. In this way the lighter fluids flowing upwardly must permeate the heavier fluids so that. an intinjiate intcrmingling is maintained'and all separation thereby prevented.

that, is claimed is A device for prevention of separation of gas in a carbonated water cooler, comprising apair of spaced end sections, a'plurality of hollowcylinders mounted in and between the end sections and forming. closed chambers therewith, one of said end sections being formed with, an inlet,one of. said end sec tions having an outlet, said inlet being of t'eatcr area than the outlet, one ofsaid end sections having. its normal: upper edge portion. formed with a plurality of transfer chambers and with inlet and outlet ducts establishing communication through said transfer chambers and between said closed chambers, corresponding inlet ductsof the respective transfer chambers being smaller than the corresponding outlet ducts of said transfer chambers, pipe sections mounted; inthe outlet ducts of the respective transfer chambers and extending downwardly through said closed chambers establishingconnnunication between said transfer, cha n hers and the bottom portion of-theclosed chambers, whereby, carbonated liquid is maintained, in said closed chambers underpressure andis conducted, serially through all ofjsaid chambers between said inlet and; outlet and ;fi'ews upwardly through all the chambers. i V In testimony whereof I have signed my name to this specification.
